Image Converter

Turn HEIC, WebP, AVIF and other images into JPG, PNG or WebP, right in your browser.

This free image converter changes photos and graphics into the format a website, app or printer will accept. Drop in HEIC photos from an iPhone, WebP or AVIF images saved from websites, old BMP or GIF files, SVG logos or TIFF scans, then pick the output you need.

Conversions to JPG, PNG and WebP run in your browser. TIFF and ICO files, and output to AVIF, GIF, BMP, TIFF or ICO, are processed on our server. You can add many files at once and download the results one by one or as a ZIP.

Which output format should you pick?

OutputBest forKeep in mind
JPGPhotos, uploads, email, printingNo transparency, so clear areas turn white
PNGScreenshots, logos, editing, transparencyLossless, so photos become large files
WebPWebsites and online shopsSmall files, but some older apps cannot open them
GIFAnimations, old sites and forums that ask for GIFUp to 256 colors, transparency fully on or off
ICOFavicons and Windows iconsSix sizes from 16 to 256 px in one file

If a site rejects your file, look for the list of accepted formats near the upload button. JPG and PNG are accepted almost everywhere, so use JPG for photos and PNG for graphics when in doubt. For a faster website, see JPG to WebP.

Each converter has its own guide with format tips, such as HEIC to JPG for iPhone photos and WebP to PNG for images saved from the web.

How this image converter handles your files

  • In your browser: JPG, PNG, WebP, AVIF, GIF, BMP, SVG and JFIF files are read on your own device and saved as JPG, PNG or WebP. HEIC and HEIF photos are decoded locally with the libheif decoder.
  • On our server: TIFF input and AVIF, GIF, BMP, TIFF or ICO output use ImageMagick. If your browser cannot save WebP, that step runs on the server too. Temporary working files are deleted right after conversion.
  • Quality: JPG and WebP output have a quality slider, set to 92% by default.
  • Orientation and metadata: photos are saved upright, and metadata such as GPS location is not copied.
  • Animation: most pairs save the first frame of an animated GIF or WebP. WebP to GIF and GIF to WebP keep every frame and its timing, up to 500 frames.
  • Icons: JPG to ICO and PNG to ICO pack six sizes into one file, and ICO to PNG saves the largest size inside an icon.
  • SVG: files are rendered at 1x, 2x or 4x its size, up to 4096 px on the longest side.
  • Limits: each file can be up to 50 MB.
